    This site allows HTML content. While learning all of HTML may feel intimidating, learning how to use a very small number of the most basic HTML "tags" is very easy. This table provides examples for each tag that is enabled on this site.

    For more information see W3C's HTML Specifications or use your favorite search engine to find other sites that explain HTML.

    Most unusual characters can be directly entered without any problems.

    If you do encounter problems, try using HTML character entities. A common example looks like &amp; for an ampersand & character. For a full list of entities see HTML's entities page. Some of the available characters include:

    Character DescriptionYou TypeYou Get
    Ampersand&amp;&

  • Syntax highlighting of source code can be enabled with the following tags:

    • Generic syntax highlighting tags: "<css>", "<html>", "<php>", "<javascript>".
    • Language specific syntax highlighting tags: "<c>" for C source code, "<cpp>" for C++ source code, "<drupal5>" for Drupal 5 source code, "<drupal6>" for Drupal 6 source code, "<java>" for Java source code, "<javascript>" for Javascript source code, "<mysql>" for MySQL source code, "<python>" for Python source code, "<ruby>" for Ruby source code.
    • PHP source code can also be enclosed in <?php ... ?> or <% ... %>, but additional options like line numbering are not possible here.

    Options and tips:

    • The language for the generic syntax highlighting tags can be specified with one of the attribute(s): type, lang, language, class. The possible values are: "c" (for C), "cpp" (for C++), "drupal5" (for Drupal 5), "drupal6" (for Drupal 6), "java" (for Java), "javascript" (for Javascript), "mysql" (for MySQL), "php" (for PHP), "python" (for Python), "ruby" (for Ruby).
    • Line numbering can be enabled/disabled with the attribute "linenumbers". Possible values are: "off" for no line numbers, "normal" for normal line numbers and "fancy" for fancy line numbers (every nth line number highlighted). The start line number can be specified with the attribute "start", which implicitly enables normal line numbering. For fancy line numbering the interval for the highlighted line numbers can be specified with the attribute "fancy", which implicitly enables fancy line numbering.
    • If the source code between the tags contains a newline (e.g. immediatly after the opening tag), the highlighted source code will be displayed as a code block. Otherwise it will be displayed inline.
    • A title can be added to a code block with the attribute "title".

    Defaults:

    • Default highlighting mode for generic syntax highlighting tags: the default language used for syntax highlighting is "php".
    • Default line numbering: no line numbers.

    Examples:

    You typeYou get
    <css>foo = "bar";</css>Inline code with the default syntax highlighting mode.
    <css>
    foo = "bar";
    baz = "foz";
    </css>
    Code block with the default syntax highlighting mode.
    <css lang="drupal6" linenumbers="normal">
    foo = "bar";
    baz = "foz";
    </css>
    Code block with syntax highlighting for Drupal 6 source code
    and normal line numbers.
    <css language="drupal6" start="23" fancy="7">
    foo = "bar";
    baz = "foz";
    </css>
    Code block with syntax highlighting for Drupal 6 source code,
    line numbers starting from 23
    and highlighted line numbers every 7th line.
    <c>
    foo = "bar";
    baz = "foz";
    </c>
    Code block with syntax highlighting for C source code.
    <c start="23" fancy="7">
    foo = "bar";
    baz = "foz";
    <c>
    Code block with syntax highlighting for C source code,
    line numbers starting from 23
    and highlighted line numbers every 7th line.
